Node.js Application Development

All HOTT courses are available face-to-face, remote-live, on-demand or on-site at your facility. 

This hands on Node.js course will teach front end designers and server side developers how to rapidly create, maintain, and deploy Node.js applications. This course includes thorough coverage of the Node.js architecture, the V8 engine and the Node Ecosystem. The course takes a practical approach to creating and organizing Node.js applications using functions and modules as part of the Node.js organizational structure. This course will provide attendees with a comprehensive understanding of Node.js core modules and how to procure and install packages using npm. Attendees will learn to identify and correct problems through unit testing and exception handling.

Attendees will learn how to use Node.js to create Command Line Interface applications for system administration and process management, use Node.js networking modules to communicate with TCP/IP clients and servers such as HTTP servers, and create / consume REST (Representational State Transfer) data services. Attendees will learn how to leverage frameworks such as Express to rapidly build Web Applications. Attendees will learn how to use Node.js to connect to NoSQL databases such as MongoDB to store, retrieve, and manipulate data (i.e., achieve data persistence).

Comprehensive hands on exercises are integrated throughout to reinforce learning and develop real competency.

Students Will Learn:

• Installation and configuration of Node.js
• Using npm to install and manage modules
• Working with the V8 Engine
• Building HTTP servers and HTTP clients
• Synchronous and asynchronous design patterns
• Building Node.js applications
• Storing application data in NoSQL databases
• Working with Web application frameworks such as Express
• Testing and Debugging Node.js applications
• Using Node.js core modules
• Using the Node.js event system and event emitters
• Interacting with the file system using buffers and streams
• Using Node.js networking API's to build internetworked applications
• Creating and consuming RESTful Web services

Course Prerequisites: 

• Knowledge of JavaScript equivalent to attending the JavaScript Programming course. 
• Attendees should also have familiarity with a Windows, Linux, or OS X command line interface as well as a basic understanding of network protocols such as HTTP.

Note: Classes do not have fixed location. Prior to each class they examine the geographical location of the enrolled students and then select a venue that will provide most convenient overall access for the students. Classes are held in hotel conference rooms and exact location is determined 2 weeks prior to the course date
